Dodge RAM: Critical Turbo Boost Sensor Problems Fixed

Had a similar issue with my 2017 Dodge 750 diesel. As someone with moderate experience working on turbocharged engines, those symptoms immediately point to turbo system problems. The engine light, jerking, and that characteristic whistling sound match exactly what I dealt with. After the turbo boost started acting unpredictable, I noticed the same increased fuel consumption and poor performance you describe. My workshop found a faulty cable connection at the turbocharger sensor. The connection had worked loose over time, causing incorrect boost pressure readings. Total repair was 95€, mainly labor costs to access and fix the connection at the intake manifold. The fix was pretty straightforward once properly diagnosed. The engine light cleared up immediately and the turbo boost returned to normal levels. To help troubleshoot your specific case, could you share: Current mileage on your vehicle, When the symptoms first appeared, If the problems occur more during cold or warm engine, Whether any recent work was done on the engine, What diagnostic codes you received This information would help determine if you are facing the same underlying issue.

After 119338 KM on the clock, I can confirm the problem was indeed related to the boost sensor system. The mechanic found a significant boost leak where the intake manifold connects to the intercooler. The repair involved replacing both the damaged turbo boost sensor and a cracked hose. The total fix cost 280€ including parts and labor. Since the repair, engine performance returned to normal, the whistling stopped completely, and the engine light has stayed off. The symptoms initially made me think it was a more serious turbo issue, but thankfully it turned out to be relatively straightforward. Would definitely recommend checking all boost-related components and connections before assuming worst-case scenarios. For reference, last full service was done 3 months ago with no issues reported at that time. The problem developed gradually over the past few weeks.

Thanks for the update on your Dodge 700. Great to hear the issue was resolved with a boost sensor replacement and fixing that intercooler connection. My situation was similar but less severe since I only needed the sensor connection repair. These boost leaks can be tricky to diagnose because the symptoms overlap with other turbo issues. The whistling noise and check engine warnings are classic signs of boost pressure problems, but finding the exact leak location often requires careful inspection of the entire air intake system. The gradual onset of symptoms matches my experience too. The performance drop and fuel consumption increase happened slowly enough that it was not immediately obvious. When the boost sensor finally fails completely, that is when most people notice the full range of symptoms. For anyone else reading this thread: If you notice irregular boost behavior combined with whistling noises, get the air intake system checked promptly. Catching boost leaks early can prevent additional wear on turbo components. Good call on having the complete system inspected rather than just replacing parts. The combined sensor and hose repair at 280€ seems reasonable given the work involved.

The diagnosis turned out spot-on. After having 119338 KM on the odometer, my boost leak suspicions were confirmed when the mechanic found damage at the intercooler connection point. The failing turbocharger sensor and cracked hose were causing incorrect pressure readings and poor performance. The repair totaled 280€ for parts and labor, replacing both the boost sensor and the damaged air intake components. Since fixing these issues, the engine runs perfectly again. No more whistling sounds, the performance is back to normal, and the check engine light has stayed off. Looking back, the symptoms definitely matched classic boost-related problems, though initially I feared worse turbo damage. The issue developed slowly over several weeks after my last service 3 months ago, where nothing unusual was noted. This experience confirms the importance of checking all boost system connections and components before assuming major turbocharger failures. For others facing similar symptoms, a thorough inspection of the entire air intake system can save significant repair costs.
